WASTE AND VENT PIPE FITTING.

To all whom it may concern.'

Be it lnown that I, IIENRY J. LUFF, a

`citizen of the United States of America, re-

siding at Cleveland, in the count-y of Cuyahoga and State of Ohio, yhaveinvented certain new and useful Improvements in lVaste and Vent PipeFittings; and I hereby declare thel following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same,

This invention relates to new and useful improvements in waste and ventpipe fittin'gs.

vThe object of this invention is to provide a fitting to be used as aconnectionbetween a vertical waste pipe and a' series of lateralbranches which will effectually prevent the siphonage of the traps atthe ends of the said branches.

My invention therefore consists in the features of construction andcombination of parts, the preferred form of which is illustrated in thedrawings, described in the specification and particularly pointed out inthe claims.

In carrying out my invention in practical use I provide one embodimentthereof which is designed to be used only on the highest fioor ofabuilding and another embodiment whichpis designed to be used on all thelower fioors. The fitting designed for use on the hi-ghest'floor isarranged so that the water closet waste pipe and waste pipes from other'fixtures may enter the vertical pipe directly and separately with thetops of the branches all on the same level and each branch thereforemayindependently receive air from the vent pipe immediately above insufficient `quantities to efi'ectually prevent the siphonage of the trapat the end thereof. The fitting which is designed to be used on allfloors below the top floor is provided with a revent chamber, the bottomof which is inopen communication with the interior of the fitting andthe closet Waste pipes and the waste pipes from the other fixturesent/er the fitting immediately below the revent chamber with their topsall on the same level and therefore each waste pipe receives airdirectly and independently from the revent chamber and the said reventchamber re- Specicaton of Letters Patent.

vent pipe communicating directly therewith and independent the wastepipe.

In the accompanying drawings Figure 1 is a view in elevation showing thebath-room fixtures on two fioors, the highest and the floor next below.Fig. 2 is a section on line 24-2, Fig. 1. Fig, 3 is a section on line33, Fig. 2. Fig. 4 is a section on line 4 4, Fig. 3. Fig. 5 is a sectionon line 5-5, Fig. 1. p

Referring now particularly to Fig. l, which shows'the generalarrangement and installation of h oth formsof my fitting, 1 representsthe top floor of a building and 2 represents1 the floor immediatelybelow, 3 represents the bath-tub and 4 a waslrstand on the top floor,and 5 represents a bathtub and 6 a wash-stand on the lower floor. 8represents a vertically arranged soil-pipe which extends from the sewerconnection to the top Hoor, the said soil pipe being formed, as iscustomary, of a number of sections, and between said sections at eachfioor is arranged one of my improved fittings, the litting indicated by10 being the style of titting which is used at all floors below the topfloor and the fitting shown at 13 being the fitting that is used at thetop or highest floor, 14 represents the main vent pipe and it extends upfrom the topmost fitting and is practically a continuation of the soilpipe, but no waste passes down therethrough. 16

tub 3 to the fitting 13 and 17 represents the waste pipe from the stand4 to the fitting 13, and in the waste pipe 16 is a trap 1G and in thewaste pipe 17 is a trap 17. In a similar way the bath-tub 5 is connectedwith the fitting 10 by a Waste pipe 19 and the stand 6 is connected withthe fitting 10 by a wastepipe 20. In the waste pipe 19 is a trap 19 andin the waste pipe 20 is a trap 20.

Referring more particularly to Figs. 2, 3 and 4 of the drawings, whereinthe form of my fitting suitable for all floors but the top floor isillustrated, it will be seen that the fitting before referred' to as 10comprises a hollow body portion 25 which is provided at A its bottomwith a hollow neck portion 27 which is made of suitable size to fit intothe hub of the Waste pipe. At the top of the represents the waste pipefrom the bathl body portion is formed an inlet opening` 28 around whichis arranged a flange 29 adapted to receiveA tli'e'lower end of thesection of" the soil-pipeabove said fitting and a suitable seal 30. isarranged between the end of the soil-pipe and said flange to prevent theescape of gas. An annular ange extends downwardly from the inner surfaceof said fitting at the top thereof dividing the inte- 1o rior ofsaidfitting at the upper part thereof intol a passageway which forms acontinu- .ation of the top inlet opening and an annular revent chamber33 which surrounds said passageway. The walls of this chamber are 1 5upwardly .arched andthe said chamber is in open communication withtheinte'rior of the fitting, there being no bottom wall whatever to thesaid chamber, and as there is no bottom wall' to said chamber there isconsef quently no place wherein solids may lodge at any time which wouldimpede the circulation of air in said chamber. Extending outwardlyfromthe main body portion7 just below the Y. revent chamber areformed anumber of'connections. These connections are adapted to receive thewaste pipes from the closetfand'` from the other fixture'. Theconnections 36 and 37 vare the `closet connections and the connections38, 39, 40 and -451 represent the l 'connections for the smallerwaste-pipes from the bath-tubs, wash-stand and other fixtures. The vtopsof all these connections are level vwith each otherso'that they allcommunicate with the revent chamber 86 equally-in proportion to theirsize. Iher closet waste-pipes,indicated'at 43 and 44, en-

ter-the `connections 36 and 37 and the bath'- tub and washstandwaste-pipes enter the connections38,39,40 and 41 so that the tops' ofall the wast-e pipes are in line with' each otlierand therefore drawtheir air fromY the revent chamber from points which are all in/inletopening 53 around which is arranged the same horizontalplane. Inthe top of the aflange 54 adapted to receive the lower end `of the ventpipe 14 and a suitable seal. 55 is arranged between the end of the ventpipe and said fiange. No revent chamberis provided in this fitting, theconnections for thewaste .pipes extending outwardly the opening to thevent pipe. Tlicse connections are all separate so that they can drawtheir air independentlyfrom the vent-pipe and the top's of all theconnections are level with each other.

shown, 57 and 58 represent the closet con- ,In Fig. 5, where thisconnection is most clearly` nectioiis, and-59, 60, 61 and 62 representthe connections for the smaller waste pipes.;

I have shown the 4'waste-pipe entering lthe l fittings horizontally, butI do not'confine myself to any particular angle at the lpoint where theyenter the iittings,as the gist of Amy -invention is the arrangement ofthe Waste-pipe enteringtlie' fittings separately .rnd with their tops inthe same horizontal ine. What I claim is,-

1. A waste-pipe fitting constructed at top 'and bottom forconnection'with the p ipel sections of a ventilated sewerage system forAt' buildings, and having intermediate its endsl a plurality of inletconnections of more than one size the internal diameters of which arethe same or dili'erent horizontal planes at bottom, according to thediameters of'said connections.

.2. The combination with 'a plurality of soil pipes from closet bowlsand waste pipes from tubs and other fixtures,- and Aa verticallyarranged sectional soil pipe, of a fitinthe same horizontal planeat topand in' ting comprising a body portion which is rovided at its top withan inlet connection or the lower end of one section of the soil pipe andat its bottom with an outlet con- .,nection for the upper end of thenext lower -a series 'of inlet .connections for the waste and soilpipes, said body` portion having an wardly from the top, said annularHange -section of the soil pipe, and at its side with 'interior 4annularlange extending downtogether with the top Wall of the fitting and theadjacent portion of the side wall formtop inlet connection and above theside inlet connections, said fitting having in the Wall thereof a ventopening which communicates ing an annular revent chamber around thedirectly and independently with said annular chamber.

' 3. The combination with a plurality of soil pi and ot er fixturesand avertically arranged sectional soil pipe, of a fitting adapted toconnect' the sections of the soil pipe and re;

es and waste pipes from closet bowls ceive the ends of, the Waste andsoil pipes,

said iitting comprising a body portion which is provided at its to withan inlet connection forthe lower en of one section of the vertical soilpipe and at its bottom with an outlet connect-ion for the upper end ofthe next lower section of the vertical soil pipe, said connections beingin vertical alinement and at its side with a series of inlet connectionsfor the waste and soil pipes, said body portion having an interiorannular flange extending downwardly from the top and forming acontinuation of the said top inlet connection, said annular' flangetogether with the .top wall of the fitting and the adjacent portion ofthe side wall forinvingan annular revent chamber aropnd the soil pipesand waste pipes from closet bowls and other fixtures and a verticallyarranged sectional soil pipe, of a fitting comprising a hollow bodyportion which is provided at its top and bottoni with connections forthe waste and soil pipes, said fitting being-also provided in itsinteriorv at the top thereof with an annularl revent ohainber arrangedaround the top inlet connection and above the side inlet connections,said annular revent chamber being entirely open at its bottom and havingin tive wall thereof a vent opening independent of the other openings inthe side fitting. j

5. A fitting of the character described comprising `a hollow bodyportion having an inlet 'connection at its top, and outlet connection atits bottom and a series of inlet connections around the side and aninterior annular flange extending downwardly from the top around the topinlet connection and dividing the linterior of the upper part 'of saidttig into a central passageway and an annular revent ehamber around thesaid passageway, said revent chamber having a vent opening in the upperpart thereof inde' pendent of said passageway.
